The subject of this study was to determine the frequency of drug use and attitudes toward drug use in Croatian high school students. The study was carried out in a middle-class high school in Zagreb. Out of 273 students who participated in an anonymous, self-report, 23-item questionnaire, 69 reported that they had at least once used drugs. The most frequently used drug was cannabis. While one third of students have been offered drugs, even 41% of the students would have take the drug if it becoms available. It can be concluded that the drugs appear to be highly available among Croatian students. According to our results, even more stronger increase in the number of drug users in Croatia could be expected
